Answer:
x = 100 meters
Step-by-step explanation:
The area of the original plot is 200 x 300 = 60,000
Doubling the area would equal to 120,000
(x + 200) x (x + 300) = 120,000
x^2 + 500x + 60000 = 120,000
x^2 + 500x - 60,000 = 0
(x + 600)(x - 100) = 0, so
x = - 600 (reject), x = 100
Therefore x = 100 meters.
I hope I could help :)
Answer:
It's mostly just definitions so be sure to write down vocab and things like that. My teacher also asked about doing the operations so make sure you are familiar with doing things such as adding and multiplying polynomials. Go over your notes and practice doing examples, it'll help a lot! Good luck! <3

Step-by-step explanation:
i did h quiz
(x - 4)(x + 2i)(x - 2i) = 0
x(x^2 + 4) - 4(x^2 + 4) = 0
x^3 + 4x - 4x^2 - 16 = 0
x^3 - 4x^2 + 4x - 16 = 0
